inverse of f(x)=arccos(1/2)

inverse

f (x) = arccos (\frac{1}{2})

None

Solution steps

arccos (a) = b \Rightarrow a = cos (b)

\frac{1}{2} = cos (y)

Solve for

x, \frac{1}{2} = cos (y)

Since the function is a constant function it has no inverse function

None

f (x) = 3 ln (2 x - x^{2})

f (x) = \frac{- x}{1 + x}

x + 13

f (x) = \frac{( x + 3 )}{2 x + 5}

4 x + 12
